Visible Light Spectrum (AQA GCSE Physics): Revision Note
Visible Light Spectrum
Each colour within the visible light spectrum corresponds to a narrow band of wavelength and frequency
The different colours of waves correspond to different wavelengths:
Red has the longest wavelength (and the lowest frequency and energy)
Violet has the shortest wavelength (and the highest frequency and energy)

Colours of the visible spectrum with increasing wavelength
Wavelength and frequency are inversely proportional, this means that:
An increase in wavelength is a decrease in frequency (towards the red end of the spectrum)
A decrease in wavelength is an increase in frequency (towards the violet end of the spectrum)
